<h3 align="center">Magick::CoderInfo</h3>
<p>The <i>CoderInfo</i> class provides the means to provide information regarding ImageMagick support for an image format (designated by a magick string). It may be used to provide support for a specific named format (provided as an argument to the constructor), or as an element of a container when format support is queried using the <a href="STL.html#coderInfoList">coderInfoList()</a> templated function.</p>
<p>The following code fragment illustrates how CoderInfo may be used.</p>
<pre class="code">
CoderInfo info("GIF"); 
cout &lt; info->name() &lt;&lt; ": (" &lt;&lt; info->description() &lt;&lt; ") : "; 
cout &lt;&lt; "Readable = "; 
if ( info->isReadable() ) 
  cout &lt;&lt; "true"; 
else 
  cout &lt;&lt; "false"; 
cout &lt;&lt; ", "; 
cout &lt;&lt; "Writable = "; 
if ( info->isWritable() ) 
  cout &lt;&lt; "true"; 
else 
  cout &lt;&lt; "false"; 
cout &lt;&lt; ", "; 
cout &lt;&lt; "Multiframe = "; 
if ( info->isMultiframe() ) 
  cout &lt;&lt; "true"; 
else 
  cout &lt;&lt; "false"; 
cout &lt;&lt; endl;
